Machine Translation Quality Metrics

Automated MT evaluation metrics are fast scalable and consistent which makes them very efficient to use. MQM Multidimensional Quality Metrics is a translation quality assessment framework enables users to customize their own metrics for quality evaluation.

QT21 has harmonised the two major frameworks for MT error analysis QT21s own MQM Multidimensional Quality Metrics and TAUS industry standard DQF Dynamic Quality Framework implemented in most localisation tools.

Machine translation quality metrics. The methodology is designed. While comprehensive human evaluation of translation output is the most effective solution the cost time and other constraints make it impractical for ongoing projects. Translation Quality Metric J2450_200508 This SAE Standard is applicable to translations of automotive service information into any target language.

The higher the values of these metrics the better the translation quality.

4 rows NIST coordinates MetricsMaTr a series of research challenge events for machine translation. What metrics can we use to measure improvement in translation quality. It includes over 100 issue types that cover all of the major translation quality evaluation metrics.

Number of edits words deletion addition and substitution required to make a machine translation match exactly to the closest reference translation in fluency and semantics TER frac E R minimum number of edits average length of reference text It is generally preferred to BLEU for estimation of sentence post-editing effort. These measures have become an essential part of the machine translation research cycle allowing rapid testing of new features and models as. The metric may be applied regardless of the source language or the method of translation ie human translation computer assisted translation or machine translation.

It was developed to create shared quality metrics system for both human and machine translation and to improve automatic translation quality estimation. In recent years a framework called multidimensional quality metrics MQM was developed for evaluating the quality of both human and machine translations. The translators based their rankings on the Multidimensional Quality Metrics Framework MQM a customizable hierarchy of translation errors.

This article provides a guide for readers interested in deepening their knowledge of the strengths and weaknesses of the different machine translation MT quality metrics and presents a methodology and tooling developed respectively by LexisNexis and its MT provider Asia Online as part of a human quality assessment framework for patent translation. Breakthrough in the field of machine translation that has been used heavily in the GALE program. MQMs fine-grained error categories address accuracy fluency terminology and style.

Eight automatic metrics are discussed in this part. Precision Recall F-measure and BLEU-n are called metrics of accuracy ie. 5 BLEU represents two features of translation quality- adequacy and fluency by calculating words or lexical precision.
